3. Watermelon

Watermelon is abundant with some of the best antioxidants, and according to Elizabeth Somer, RD, a dietitian in Salem, Oregon:

Watermelon has more lycopene than do tomatoes — up to 20 milligrams in each 2-cup serving. The lycopene in watermelon helps lower the risk for inflammation associated with dementia and possibly depression.

Try chopping up your watermelon and keeping it in your fridge for a handy snack, or blend it up with a bit of water for a refreshing slushy.

5. Papaya

It is also filled with folic acid, which has been linked to lowering symptoms of depression.

Try having a bowl of papaya for your mid-morning or mid-afternoon snack, or add some papaya to a fresh fruit salad for added nutrients.

While you should always consult a mental health professional before taking treatment into your own hands, consider eating a diet rich in fruits and vegetables that contain antioxidants such as the ones listed.

Mental health should not be taken lightly. But the next time you're at the store, try picking up these antioxidant-rich foods to see if they help boost your mood and long-term health.
